Tinkering with The Gene Pool

Q

I have read that Satan and his cohorts were tinkering with the gene pool before the flood. What made them stop tinkering after the flood? Or did they?

A

There’s Biblical evidence that his tinkering continued after the flood. The Israelites encountered Nephilim when they entered the Promised Land. (Numbers 13:31-33) And some believe that the UFO sightings in our lifetimes indicate a return of the Nephilim in the last days.
